From 014aa7261e29810b35b3d65c759f9d255bf8a277 Mon Sep 17 00:00:00 2001 From: Ton Roosendaal Date: Mon, 9 Jan 2006 00:40:35 +0000 Subject: Orange branch: OpenEXR finally in Blender! Credits go to Gernot Ziegler, who originally coded EXR support, and to Austin Benesh for bringing it further. Kent Mein provided a lot of code for integrating float buffers in Blender imbuf and ImBuf API cleanup, and provided Make and Scons and static linking. At this moment; the EXR libraries are a *dependency*, so you cannot get the Orange branch compiled without having OpenEXR installed. Get the (precompiled or sources) stuff from www.openexr.com. Current default is that the headers and lib resides in /user/local/ Several changes/additions/fixes were added: - EXR code only supported 'half' format (16 bits per channel). I've added float writing, but for reading it I need tomorrow. :) - Quite some clumsy copying of data happened in EXR code. - cleaned up the api calls already a bit, preparing for more advanced support - Zbuffers were saved 16 bits, now 32 bits - automatic adding of .exr extensions went wrong Imbuf: - added proper imbuf->flags and imbuf->mall support for float buffers, it was created for *each* imbuf. :) - found bugs for float buffers in scaling and flipping. Code there will need more checks still - imbuf also needs to be verified to behave properly when no 32 bits rect exists (for saving for example) TODO: - support internal float images for textures, backbuf, AO probes, and display in Image window Hope this commit won't screwup syncing with bf-blender... :/ --- source/blender/imbuf/intern/writeimage.c | 27 +++++++++++++++++---------- 1 file changed, 17 insertions(+), 10 deletions(-) (limited to 'source/blender/imbuf/intern/writeimage.c') diff --git a/source/blender/imbuf/intern/writeimage.c b/source/blender/imbuf/intern/writeimage.c index 340f8ace415..b752dbf9dd0 100644 --- a/source/blender/imbuf/intern/writeimage.c +++ b/source/blender/imbuf/intern/writeimage.c @@ -57,12 +57,15 @@ #include "IMB_bmp.h" #include "IMB_tiff.h" #include "IMB_radiance_hdr.h" +#ifdef WITH_OPENEXR +#include "openexr/openexr_api.h" +#endif #include "IMB_iff.h" #include "IMB_bitplanes.h" #include "IMB_divers.h" -short IMB_saveiff(struct ImBuf *ibuf,char *naam,int flags) +short IMB_saveiff(struct ImBuf *ibuf, char *name, int flags) { short ok=TRUE,delpl=FALSE; int file = -1; @@ -72,28 +75,33 @@ short IMB_saveiff(struct ImBuf *ibuf,char *naam,int flags) /* Put formats that take a filename here */ if (IS_jpg(ibuf)) { - return imb_savejpeg(ibuf, naam, flags); + return imb_savejpeg(ibuf, name, flags); } if (IS_radhdr(ibuf)) { - return imb_savehdr(ibuf, naam, flags); + return imb_savehdr(ibuf, name, flags); } if (IS_png(ibuf)) { - return imb_savepng(ibuf,naam,flags); + return imb_savepng(ibuf, name, flags); } if (IS_bmp(ibuf)) { - return imb_savebmp(ibuf,naam,flags); + return imb_savebmp(ibuf, name, flags); } if (IS_tga(ibuf)) { - return imb_savetarga(ibuf,naam,flags); + return imb_savetarga(ibuf, name, flags); } if (IS_iris(ibuf)) { - return imb_saveiris(ibuf,naam,flags); + return imb_saveiris(ibuf, name, flags); } if (G.have_libtiff && IS_tiff(ibuf)) { - return imb_savetiff(ibuf,naam,flags); + return imb_savetiff(ibuf, name, flags); + } +#ifdef WITH_OPENEXR + if (IS_openexr(ibuf)) { + return imb_save_openexr_half(ibuf, name, flags); } +#endif - file = open(naam, O_BINARY | O_RDWR | O_CREAT | O_TRUNC, 0666); + file = open(name, O_BINARY | O_RDWR | O_CREAT | O_TRUNC, 0666); if (file < 0) return (FALSE); if (flags & IB_rect){ @@ -103,7 +111,6 @@ short IMB_saveiff(struct ImBuf *ibuf,char *naam,int flags) } /* Put formats that take a filehandle here */ - ok = imb_start_iff(ibuf,file); if (IS_amiga(ibuf)){ IMB_flipy(ibuf); -- cgit v1.2.3
